I hope more and more developers start to realize that the 360 pad isn't the default controller anymore. They likely already have assets available for the PS4 version of the game, so include Playstation button prompts with the release. Allow us to switch between our preferences within the menu system.
Transistor did this in a way, Supergiant natively supported the DS4 out of the box including prompts and use of the lightbar.
You think there are more people using the PS4 controller than the 360 controller? The 360 controller is going to be the "default" for a long time.
